Every dredging project needs a pump

In the past, Martens en Van Oord had to put together a pump and a motor for every dredging project. Now, they have found a solution that means only the pump needs to be changed, not the whole solution.

Their innovation is a motor with an integral 1 MW FDU built into a container. Since this frequency inverter can be used to drive various pumps, the unit is easily adapted for use in different projects, simply by changing the pump.

Reliable solution and good service

 When creating this new adaptable solution, Martens en Van Oord sourced the drives from CG Drives. Their decision was based on a positive previous experience of the company.  Martens en Van Oord earlier bought approximately 30 Emotron drives for use in a sand factory in Moerdijk, and these proved very reliable over the long-term.

Their positive experience also extended to the excellent service provided by CG's flexible organisation. Says one spokesperson from Martens en Van Oord, “CG takes care of the start-up, and provides support when installations are changed. You're NOT alone! Furthermore, the drive has a very simple parameter structure, making it easy to set up and use.”
